Your P/S is a brute. Short-Circuit protection should have kick-in and save the day.
A fuse should be mandatory in any high power design. In this case, miner.
Didn't see any so far, and many manufacturers out there. Huh

My PSU is the Bitmain APW3+-12-1600W, It says it has every protection. but it failed. Sad

A waste of money.

Not only crap miners, but crap PSU's. Way to go Bitmain

Ah I just read this, it's the shit power supply Bitmain sells that fucked up, not the miners. I guess that's a relief that it's their psu's and not miners that are randomly catching fire lol. Makes sense I suppose.

Definitely go with some good server power supplies in the future.

Just *how* is an obvious failure of the hash board Vcore regulator -- probably the MOSFET's shorting -- the fault of a PSU? Just what in a PSU do you assume could have prevented this?

The Bitmain PSU can supply up to 133A continuously and probably at least 10-15% more before tripping out, the combined maximum current rating of 3x PCIe connectors is only 81 amps. Vcore regulator blew, all power took the easiest path - through the short circuit - and so yes, the connectors and wiring smoked. For what it's worth, I have 25 of the AWP1300 supplies and have had ZERO problems with them. Don't know about the newer APW1300+ but the older ones are very well made.

Now should all miners have a fuse between the power sockets and Vcore? IMHO yes they should but that is just speaking as an Engineer with over 50 years of dealing with power electronics...

How do I add a fuse between the PSU and Miner? Do you know any electronics? How many ampere should I put? I have 3 S9's coming. I would like to protect it. Its very frustrating to see my investment just get burned. tsk.

Simple equation is Power in watt ( P ) = Voltage ( V ) * Ampere ( A )
or
P = VA
or
A = P/V

1600W / 12 V = 133A

133A / 3 Boards = 44A

Rules of thumb you rate your fuse x2

80A Fuse with enough DC voltage rating will do a good job.

Need a breakout board and extra cables

I didn't fused mine. I use high quality EVGA 1300 supply with working protections.
Over-Voltage, Under-Voltage, Short Output, Over Temp, Good voltage regulation and 10years warranty.
Expensive but I sleep better.

For few extra bucks, manufacturer fail to add safety to save money.

Will definitely do this. thanks for the info. Is a 1300w PSU enough to power the S9?

Will this do?

Get one of these 1500w server power supplies. Mining is what these puppies were made for: http://www.ebay.com/itm/684532-B21-684529-001-HP-1500W-CS-Platinum-Plus-Hot-Plug-Power-Supply-/252627974019
Then get a breakout board to make it work with the miners: http://www.ebay.com/itm/Breakout-Board-Adapter-for-HP-1200w-DPS-1200FB-Power-Supply-Bitcoin-Antminer-/231948229211?hash=item3601311a5b:g:f0UAAOSwcvdXO6By

Not the best of ideas to go with a power supply that is meant to be used in home computers, pushed not nearly as hard, for not nearly as long as you'll be using them for. Plus these are WAY cheaper. Cheesy

I use a combo
1x 1300W -> Board 1 + 2
and
1x 1000W -> Board 3 + Controller

Running on 220V.

1x 1300W won't be enough

Power supply is where you do not want to cheap out. I learned that when investigating PSUs. I ended up going with an EVGA 1600 T2 because of these vital components. Not only are we talking about a $2000 computer, but potentially my house if a fire started.

points taken. Sad

I used Bitmain APW3+-12-1600W.

Two of my S9 11.85TH 550M Hashboards.. Sad

My S9 pass through a 2000VA AVR. The Control board, Power Supply is still functioning. Why did it happened? Is it still repairable?

Are your guys S9's really just spontaneously catching fire??? Were they running too hot? Malfunction with the power supply? Anything other than they just randomly caught fire?

Maybe 1400 each.

How many TH/s?

don't remember as I run them under clocked

one is a 650
the other is a 550

one is doing 14th right now -------------- manual
the other is doing 12.2th right now ------ manual

third unit is 1 s-9 board the other 2 board are dead and buried. ---- plus I don't remember if it is auto tune or manual
